“So let us come boldly to the throne of our gracious God. There we will receive his mercy, and we will find grace to help us when we need it most.” (Hebrews 4:16 NLT)
In other words, on the day when we are called, the Lord will be there to help us. As our souls enter heaven (or whatever is waiting for us!) he will be there.
And that gives us (or SHOULD give us) the confidence to step up and be counted.
